The design and test of the carbon fiber embedded framework and the corresponding structure board of SAST 5000 platform are studied. The topological optimization of the embedded frame structure and the use of carbon fiber materials were analyzed. The optimized structural plate modal and static state were analyzed. The static test and flaw detection of the whole plate were carried out. The results show that on the basis of the installation of the metal frame in the scheme stage, the weight of the installation plate of the tank is greatly reduced by the topological optimization of the embedded frame structure and the use of the carbon fiber material, the simulation analysis and the test description Carbon fiber embedded frame tank mounting plate mechanical properties to meet the satellite bearing requirements.
